We do not have to collect tax for purchases shipping outside the state of GA. Once shipped, ground orders take 2-3 business days to get to NJ. If the order is under 150 lbs, the order will be shipped ground and the delivery will be to your front door!
The sanagloss is already included. That is the G at the end of the model number. I am not sure why it says sanagloss is optional. It's on all the newer Toto models.
